MDEV-33837: Fix lintian warning that are against debian/control

Debian control file has few lintian warning level notifications

 * mariadb-test: breaks-without-version mariadb-server-5.5
   - Several packages conflicts with mariadb-server-5.5 but
     on mariadb-test breaks without it so it's controversial
     and can be resolved only with conflicting in mariadb-test

 * W: libmariadbd-dev: extended-description-line-too-long line 6
 * W: mariadb-plugin-cracklib-password-check: extended-description-line-too-long line 4
   - Lines are too long (over 80 chars) and they are just separated
     to new line.
